Air Purifiers

I own a mitsubishi lancer 2003, if i put an air filter or pod filter will that increase my kw? if so by how much?

I had just gotten a flameless scented candle and really love it. I also have an air filter in my room. The one where it’s certain metal that attract ions and the dust sticks to it, thus filtering the air.

I was wondering, if I have both of those on at the same time, will it filter out the good scent or will it pass through?

I drive a 2004 Chevy Malibu Classic and i wanted to know how often are u suppose to change the air filter?

I recently purchased a 2006 ninja 650r that would turn over but not fire. The battery is fully charged, there’s fresh fuel in the tank, I have spark at the plugs, the fuel pump is working fine, and there’s good compression. I did notice that the air filter is pretty dirty. Would something that simple be enough to keep the engine from firing?
Pulled the filter and it still doesn’t run. I guess it’ll go into the shop next……

trying to save mula, i already have the new air filter, just scared i might mess something up, help….

I love using aromatherapy (but very new to it) and currently I am using a small glass dish with a tea-light to heat the oils. Now I want to get an air filter/purifier to clean the air in my home office (where I also use the aromatherapy oils). When I use the air cleaner/purifier, will it "clean" the scent of my aromatherapy, basically making it useless and a waste to heat the oils?

I have a 2007 Polaris Hawkeye ATV and I use a pressure washer to clean it. The air filter under the seat got wet and it can’t breathe. I ordered a filter from polaris and it will be here in a month. Next week, I need to use the ATV immediately. What can I put in place of the Air Filter? Please Help!

I learned that the Sharp air purifiers’ HEPA filters have an Apatite component to it that apparently provides antibacterial properties to protect the filters from microbial accumulation. Is Apatite a relatively "safe" material to use for an air filter, i.e. is it safe for the resident who is breathing air that comes through the filter? Apatite (a very general term) is usually made up of phosphorus and calcium, but some variants (ie. arsenates like mimemite) may contain arsenic. Could this be a health issue for users? Would the filters use arsenic-based variants in the first place, or are other forms more prevalent and likely to be used in medical/industrial applications?

I have a GoPed sport, stock, Zenoah LH 2003 engine, I lost my air filter the other day and need to ride it for about 2 hours or so. Will this ruin the engine?
What about if I add a piece of fabric cloth (cut a square out of a sock) and rubber-band it over the intake hole?

I have a 2007 Hyundai accent and Im thinking about getting either a K & N air filter or a cold air intake. Would either of them increase my horse power/gas mileage? And what one is cheaper?
also, does a cold intake require a hood scoop or other "tricking out"? Im only keeping it till i get me a truck.
